140V CMOS Rail-to-Rail
Output, Picoamp Input
Current Op Amp
Description
The LTC^®6090 is a high voltage precision operational
amplifier. The low noise, low bias current input stage is
ideal for high gain configurations. The LTC6090 has low
input offset voltage, a rail-to-rail output stage, and can be
run from a single 140V or split ±70V supplies.
The LTC6090 is internally protected against overtempera-
ture conditions. A thermal warning output, TFLAG, goes
active when the die temperature approaches 150°C. The
output stage can be turned off with the output disable pin
OD. By tying the OD pin to the thermal warning output,
the part will disable the output stage when it is out of the
safe operating area. These pins easily interface to any
logic family.
The LTC6090 is unity gain stable with up to a 200pF output
capacitor. A wide input and output common mode range
along with many features makes the LTC6090 useful for
many high voltage applications.
The LTC6090 is available in an 8-lead SO and 16-lead
TSSOP with exposed pad for low thermal resistance.
